Does anyone know a reason why I can't remove the
G8018's and G8019 and
replace them with newer OEM power supplies? I know that one G8018
supplies
5V @ 25a, +15V @ 2a, -15V @ 2a and +20V @ 4a. I believe the 20V is only
used
for core memory. So.a 5v supply @ 50a should be sufficient, and a 2 dual
output +/- 15v supply @ 2@ each should be a reasonable substitute. I am
aware of the functions of the G8019 and that I would be defeating the
"dead
fan shutdown" and battery backup feature.
I think a GOOD (seventeam or thermaltake, e.g.) PC power supply can do
wonders here:
- 5V you can use straight
- +15V you can mod the power supply to have it
- -15 you just change the 7912 inside the psu for a 7915
- +20V would be easier to get thru an external notebook power supply
Of course, you can always use a +5 power supply along with a +/-15V
power supply and a 19.5 power supply :)
Good luck!
